Your screen app may be interfering with the double tap to wake. Double tap to wake works fine for me. Quick tap on the back works if I generally use a less thicker case.
For the 30w charging, it's not designed to charge the phone super fast. It will charge to 50% in 30 min and then after it will slowly charge to 100. Assuming adaptive charging is turned off in settings.
The Google Pixel 6 and Pixel 6 Pro charging is oddly slow despite talk of 30W speeds, taking nearly two hours to fully charge. Here's why.

Also I call big BS on this one. The fingerprint reader is slow because it's more secure..haha.

I think I can't return the phone anymore. But I'm really disappointed in the battery life. My friend with a S21 ultra has every feature turned on, streams music all the time, watches YouTube and everything else. He's getting close to 6hrs or more of screen time and his device by the time he charges it, it's usually still 50%, mixed wifi and mobile data.
I sometimes stream music on YouTube music(1hr), or use maps a little, browse mostly, send texts, all on wifi all day. Usually by the time I need to charge I'm already under 25% and only just making it to 4hrs or 4hr 30 min of screen time. So I've come to the conclusion that the battery life isn't really any better than my 4XL, and we'll that's disappointing considering it has a 5000mah battery.
I need the phone to last me until at least 10-11pm every day off the charger at 7am with mixed usage. It's really cutting it close and I don't like being below 20% every day at the end of the day. Not even sure if that's good for the battery.
